high Nessus Plugin ID 145001

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of net-snmp installed on the remote host is prior to 5.5-60.22. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1465 advisory.

- Net-SNMP through 5.7.3 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root. (CVE-2020-15862)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update net-snmp' to update your system.
